Abstract
In a touch module, a ultrasonic wave emitted by the ultrasonic generator undergoes a total reflection in the third substrate. When a location of the second substrate is pressed to contact a location of the third substrate, a part of the ultrasonic wave undergoing the total reflection in the third substrate escapes out of the third substrate, and an intensity of the ultrasonic wave received by the ultrasonic receiver, corresponding to a contacted location on the third substrate, becomes weak, and a pressed location on the second substrate is determined by detecting a condition where the intensity of the ultrasonic wave received by the ultrasonic receiver becomes weak during loading a touch scan signal in turn on the touch scanning lines.
